Description

The invention relates to devices for the mechanical milking of animals.

A device for supplying milking cups to the teats of the udder of cows is known, consisting of a vertical stand equipped with a floating sleeve, to the upper part of which a balancing weight is attached to the upper part of a cable thrown over a roller. A horizontal telescopic boom is fixed on the vertical floating sleeve, on the end of the rod of which the suspended part of the milking machine is installed. For removal of the teat cups after completion of milking, a copier made in the form of an inclined washer is attached to the vertical stand. However, in such a device, the above-mentioned copier is unreliable in operation, due to which the horizontal boom is not removed from under the cow, which, when exiting, damages the telescopic parts of the boom.

It is also known a device for removal of the suspended part of the milking machine, consisting of a three-link hinge mechanism, at the end of the free link of which the suspended part of the milking machine is attached. From under the cow, the teat cups are led out by a pneumatic cylinder located in the passage of the milking machine.

is not regulated because the leading link of the three-link hinge is directly connected to the pneumatic cylinder rod and copying of the udder oscillations is excluded. In addition, the device cannot milk cows with a lower udder location, since when removed, the glasses, hanging down, can become contaminated with manure. It is also known a device for the supply and

removal of teat cups to the udder of the cow, consisting of an articulated three-link arm, driven by the action of two power cylinders, and the holder of the suspended part of the milking machine. This device is complicated in construction.

The proposed holder differs from the known ones in order to increase the operational reliability and improve the milking process, its middle link is connected to

driven by a half-frame mechanism, hinged on the driving link and connected to the drive cylinder by a flexible link, on which a double-arm lever is hinged, one end of which is provided with a unloading device, for example, a spring, and the second link is fixed to the second, and the half-frame a double-arm lever is connected by a pneumatic cylinder. In addition, the middle link of the articulated rifle coupling, and the end of the cylinder rod of the turn of the leading link is located in the link lever freely and provided with a stop, one-way interacting with the latter.

Advantageously, the proposed holder of the suspended part of the milking machine is capable of copying the position of the udder of the cow during milking in the event of a cow moving in the flock. This improves the milking process and provides a more complete cow delivery. It is ensured that the milking machine is properly oriented after putting the teat cups on the cow, which creates normal conditions for milk production. In addition, in case of accidental fall of the milking machine from the udder, the cow will not damage the power elements of the holder, since they are placed outside the milking machine. The holder of the suspended part of the milking equipment provides the final operation of the milking, the mechanical doda of KopOiBbi, which can be performed automatically with the help of the milking machine.

FIG. 1 shows the holder of the attachment part of a milking machine for the “Herringbone” milking machine; in fig. 2 - the same, for the milking plant of tina “Tandem.

The holder consists of a three-link lever mechanism containing a leading, middle and free link, 1, 2, and 3, respectively. On the free link 3, the fixture 4 is held to hold the suspension part of the milking machine. The middle link 2 has a handle 5 for turning it and connects to the driver link 1 by means of a copying mechanism consisting of a nuraramka 6 fixed with the help of a hinge 7 on the driving link 1, a curved double-arm lever 8 fixed on the upper side of the half-frame in the hinge 9. To one of the legs of the lever 8 by means of the friction clutch 10 krenits middle Link 2. The same rod is fixed to the rod 11 of the pneumatic cylinder 12 fixed on the half-half. 6. The other arm of the lever 8 is provided with a spring 13 unloading device, which instead of s set counterweight. The copying mechanism is rotated by a lever 14 connected by a flexible thrust 15, passing inside the tubular driving link 1, to a driving pneumatic cylinder 16, which is connected by a hose 17 to an electromagnetic valve 18. The driving link is rotated in the joints 19 by means of a pneumatic cylinder 20 acting on the lever 21 of the leading link 1. The pneumatic cylinder 12 is connected to the solenoid valve 22. The pneumatic cylinder 20 can be connected to the vacuum pipe 23 by means of the electromagnetic valve 24 by the hose 25.

was under the udder, and the lever 5, depending on bridges on the inclination of the nipples of the cow, turns the middle link 2 in the fractional clutch 10, adjusting the slope of the milking machines, and puts the teat cups on the sozzi. At the same time, the end of the middle link 2 rises, turning in joint 9.

Before the milking is finished by the milking mate or manually, the solenoid valve 22 is turned on, which periodically injects atmospheric air into the pneumatic cylinder 12 and reports the pneumatic cylinder with a vacuum wire 23 of the milking installation. This is followed by a mechanical doda - periodically pulling the milking machine down, eliminating the crawling of the milking cups on the nipples and removing residual milk from the udder.

After cessation of the milk flow, the cow milking machine or manually the spraying chamber of the teat cup is disconnected from the vacuum, and the solenoid valve 18 is turned on, connecting Pneumatic cylinder 16 and

Pneumatic cylinder 20 with vacuum wire. The teat cups fall from the udder of the cow, and the suspended part of the milking machine is removed from under the cow. These operations can be carried out sequentially: first, by the solenoid valve 18, the vacuum wire 23 is connected to the pneumatic cylinder 16, while the middle link 2 is rotated, and by the solenoid valve 24, the vacuum pipe 23 through the 25 ss hose unites with

pneumatic cylinder 20, removing the suspended part of the milking machine from under the udder. In this case, pneumatic cylinder 20 can be used simultaneously to open the doors of the milking machine. Option holder

(Fig. 2) is used in milking machines of the type "Tandem. It has the same device copying mechanism; its driving link 1 is fixedly hinged on the pivoting lever 26, which is connected with the pneumatic cylinder stem 20, and is acted by the support 27 fixed to it on the lever 28 of the driving link 1.
